Data sources were the cohort datasets of National Health Insurance Research Database with claims data in 2010. The generic prescribing ratios of dihydropyridine (DHP) derivatives (the proportion of DHP prescribed as generics to all prescribed DHP) of medical facilities were examined against the urbanization levels of the clinic location. Among the total 21,606,914 defined daily doses of DHP, 35.7% belonged to generics. The aggregate generic prescribing ratio rose from 6.7% at academic medical centers to 15.3% at regional hospitals, 29.4% at community hospital, and 66.1% at physician clinics. Among physician clinics, the generic prescribing ratio in urban areas was 63.9 \u00b1 41.0% (mean \u00b1 standard deviation), lower than that in suburban (69.6 \u00b1 38.7%) and in rural (74.1% \u00b1 35.3%). After adjusting the related factors in the linear regression model, generic prescribing ratios of suburban and rural clinics were significantly higher than those of urban clinics (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>\u03b2<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.043<\/mml:mn><\/mml:math>and 0.077;<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.024<\/mml:mn><\/mml:math>and 0.008, resp.).
